[Stoves] Hypothesis for Wonderwerk TLUD-ND

Kirk,

The Wonderwerk Man has again done wonderful work!!!!   Stove Summit, 
Stove Camp, assisting Dennis (who then won the Cat Pee award), and 
cooking with Flip.  It is always a pleasure being with you.

The hypothesis (explanatory document) is well done.  All serious stove 
researchers should read it.  Where is this document being placed for 
public access.   I offer to place it at the drtlud.com   website.  (Send 
your reply to James Schoner directly or via the Stoves Listserv; I will 
be in Mexico for the next 13 days).

Hypotheses are statements that ask to be confirmed.  The folks with the 
scientific equipment can now step in and see if the long-chain 
hydrocarbons are indeed breaking up when and where indicated by the 
hypothesis.  Good if that could be soon, but I expect not.  In the 
meantime, the excellent low emissions (which are facts, not hypotheses) 
speak for themselves.

The needed scientific studies would help answer several questions such 
as whether all three steps (levels) are needed to accomplish the low 
emissions and the ability for turn-down to low fire.

About turndown such as when cooking in Flip's oven, a different solution 
is to have a second gasifier reactor (fuel chamber) that has a smaller 
diameter.

Keep up the good work!!   (werk)

Paul
